Limb boiler.

The present articulated boiler is intended to be used for production with a relatively small wall thickness high tensioned steam, which takes the shortest route to the steam collector is directed and causes a natural circulation. '

The articulated boiler is shown in the accompanying drawings, namely in Fig. 1 in Front view, in Fig. 2 in vertical section along line 2-2 of Fig. 3, in Fig. 3 'in longitudinal section along line 3-3 of Fig. 2. In Fig. 4 is the end view of one of the individual boiler elements given on an enlarged scale, in Fig. 5 that for the production of an element prepared sheet metal in plan, in Fig. 6 the same in end view, in Fig. 7 the end view a modification of the element, in Fig. 8 a longitudinal section through an element between the collecting tubes on an enlarged scale and in FIG. 9 a longitudinal section through two articulated boilers arranged one behind the other with a common chimney.

As can be seen from Fig. 2, the boiler is composed of the elements BCDEFG , of which the outer B and C extend down to the grate of the furnace A and form its side walls. These elements rest on the iron girders a, while the inner elements are suspended above the grate. The elements represent vertical, tubular bodies and consist of connected sheet metal plates, which are first brought into the shape shown in FIGS. 5 and 6, whereupon the middle part h is bent to form a hollow cylinder, FIG. 4. Two each fall waves g and form 'b a cavity, Fig. 8. the two plate halves are then riveted together and the outward lobes h of the plate. Fig. 5 and 6, bent, that they with the k by rivets I held Gufsstück i a second hollow cylinder H form. The latter is provided with as many cleaning holes e as there are cavities b.

As shown in FIG. 3, the elements combined to form a vessel are in such a position that the cavities bb are vertical and the hollow cylinder H, lying horizontally, the collecting pipe for the one rising from the cavities bb. Forms steam. The hollow cylinder I , which is inclined to H , will therefore also have an inclined position. It forms a second collecting pipe through which water is supplied to the cavities, spaces bb.

For the purpose of connecting the pipe socket M , the collecting pipes H and / by means of a fitting piece m are brought into an exactly cylindrical shape at the ends, Fig. 4. The rear end of the collecting pipe H is passed through the cover O without a pipe socket, the front socket M of the same by a cover N, the remaining nozzle closed by cover f , Fig. Ι and 3,

The individual boiler elements are connected at the front end by a transverse feed pipe J and at the rear end by a sludge bag K. The manifold H of each inner element is in communication with the steam collector L through a pipe c and that of the outer elements with the same through pipe d.

In the modification of a boiler element shown in FIG. 7, the cast piece i of FIG. 4 has been replaced by a conventional overlapping, riveting ο. By arranging a third collecting pipe P, which is connected to the collecting pipe H through the cavities ρ, an enlargement of the water space has been achieved, as is necessary with ship boilers, the normal water level of which must be set higher due to the fluctuations of the vehicle. For the purpose of uniformly feeding all sections of the boiler, the feed pipe .Q, Fig. 1, has been widened to a reservoir J; the feed water that collects in the same passes through the pipes u into the outer, and through the pipes n> into the inner collecting pipes I. On the other hand, the reservoir J is connected to the upper collecting pipe H through the pipes ν. So that the condensation water that forms in the steam collector L can flow back to the water space, it is connected to one of the collecting pipes H by pipe χ. The sludge that settles in the boiler passes through the pipes y into the sludge bag K. All boiler elements. The fire bridge S surrounds the air shaft T, which ends in the gap t below ... the projection U '■. This: I is made of refractory material above the .S. collector pipes / listed, Fig. 3, and forms the; lower edge of the exhaust opening: F, which can be more or less closed to regulate the draft by the flap s. -, The conclusion. the: firing -after; above is achieved by filling the gaps w between the headers H with refractory material, and the space above the face plate -R between the headers H and I is walled up. The one on the. Combustion gases developed from rust are completely burned by the supply of oxygen by means of the air stream emerging from the gap before they escape through the chimney. . .; Fig. 9 shows the combination of two kettles. whose flue gases are discharged from a communal chimney. : The present articulated boiler is intended to provide the following advantages: Analogously to the safety boilers, the water is distributed over individual chambers, so that the wall thicknesses are very small, while at the same time a very large evaporation surface is formed. However, the many sealing surfaces that are unavoidable in safety boilers are no longer required. The steam bubbles developing from the water are not forced to overcome the friction on the pipe walls on a long way to the steam room. In addition, every point inside the steam generator is accessible, so that cleaning and repairs can be carried out with ease. No seam is exposed to the destructive, disruptive effect of the fire gases. As complete a combustion as possible is achieved by supplying heated air. Pat en τ-An Proverbs: ' 1.
